DEVICE :FOR FASTENING SHINGLES.

Application med Irch, 1925. serial No. 13311,

My invention relates to devices useful in fastening shin les in place, more especially shingles lappe in 'the ordinary Way as distinguished from those adapted to be lard o diagonally.

The main object of my invention is to enable ordinary lap shingles to be fastened to the supportin Structure of a roof with their exposed en s restrained from displacement against wind pressure.

, How this desideratum may be obtamed, together With other advantages, Will be readily understood from the detailed de scription which follows of typical embed]- 1 ments of my invention; while its scope Wlll be as readily deductible from the appended claims.

In the drawings, Fi I is a fragment of a roof with lapped s ingles Secured with fastening devices of my invention.

Fig. II is a view in perspectiva on a larger scale ?if the fastening' devices shown in Fig. I' an Fig. III is a similar view of a slightly modified form of my invention.

As shown to best advantage in Figs. II and III of the drawings, my improved shin- 'gle fastening device may be generally and briefly described as comprising securlng means in the form of reversely angled or right and left hand prongs 1, 1, a shank comprehnsively designated by the numeral 2, and otfsets or projections 3-3 extendin'g .laterally from the end of said shank. Suoh a device may obviously be made in a number ot' different ways; but for convenience and economy of manufacture, I prefer to construct it of a single piece of wire sufliciently stout or heavy toserve the purpose 49 -for which the device is intended. The form of Fig. II may be produced 'by bendin'g the Wire to the configuration there shown, With the ends of the wires serving as the prongs 1, 1, turned downwardly from lateral extensions 4-4 of parallel bars 5-5 which constitute the shank 2 preV-iously referred to; While the latcral ofl'sets or projections 3-3 'are afl'orded by formin the wire into a comparatively flat triangular loop 6. The bars to serve as gauges in determining the lateral spacing of the shingles as will become apparent from further description. The ends of the prongs 1, 1 are reduced to the 5-5 may b'e disposed in slight separation form of points so that they may be readily driven' by a hammer in securin the shingles; While the loop 6 is preferab raised Ol' ofl'set somewhat above the plane o the shank 2 to allow for the thickness of the shingle material. The latter of these provisions may be instituted by joggling as indicated at '3-7 incidentally to the manufacture of the evice.

The modification of Fig. III diflers from' the form just described in detail only, in

'that the two bars of the shank 2 are twisted together as suggestedin the illustration, for greater rigidity of the fastener as a whole.

In onstructing a roof with the aid of fastenlng devices of my invention, the procedure is as follows:

The shingles indicated by the letter 'S" in Fig. I ate laid in the usual super osed apped relation, and, either incidenta y'to the handling of the individual shingles, or after' a complete course is laid, the fastening devices are allocated so that their shanks 2 are ali ed with the Vertical media] of the sh ng es; prongs 1, 1, ma be driven approximately centrall throug those portions of the shingles which are to be subsequently overlapped. A succeeding course is then superposed upon the first in the desired lapped relation, Secured in the same manner as before, and the exposed ends of adjacent pairs incidentally enga ed for retainment against displacement, eneath the lateral projections 3-3 at the lower ends of the shanks 2, 2 of the fastening devices of the subjacent course. It will at once be obvious that as a result of the oifsetting or Jogglmg of the loops 6 relative to' the shanks 2, the latter are permitted to lie, throughout their length, directly against the shingle surfaces, thereby enhancing the 'securing eect of the device.

Although' I have herein shown and described my invention in connection with the laying individual shingles S, they maybe A used with equal advantages in securing shingles of Strip form as long as theirposition with respect to the shingle tips is so ordered that they function in the capacity cxplained.

Having thus described my invention, I claim:

1. A fastening device for shingles fabricated' from a single piece of wire to provide reversely angled prongs for penetrating that ortion of the shingle normally overlapped and to secure the same on a supportingstructure, a shank adapted to repose in the interval of a pair of adjacent shingles of a superposed Course, and an ofl'set terminal loop atfordng opposed project'ions functional to grip the side edges of said adjoining shingles and restrain them against displacement.

-2. A 'fastening device for shingles fabricated from a single piece of Wire to provide reversely angled prongs for penetrating that portion of the shingle normally overlapped and to secure the same on a supporting Structure,' a downwardly directed shank adapted to repose in the interval between a pair of adjacent shingles of a: superposed Course, and an otfset. terminal loop atfording lateral pr0 jections functional to grip the side edges of said adjoining shingles and restrain them against displacement.

3. A fastening device for shingles fabricated from a single piece of Wire to provide reversely angled prongs for penetrating that portion of the shingle normally overlapped and to secure the same on a supporting Structure, a downwardly directed shank adapted to repose in the'interval between a pair of adjacent shingles of a superposed course, and an oiset terminal loop at the lower extremity of the shank afl'ording lateral projections functional to grip the side edges of said adjoining 'shingles and restrain them against displacement.

4. As a new article of manufacture a fastening device for shingles fabricated from a single piece of Wire to provide paralleled 'shank m mbers having reversely angled atv ing reversely angled attaching prongs at one end and a triangular expanded ofl'set affording opposed gripping projections at the other end; l
